Re: hazing H&E's

Fred, I replied directly to Amy and thought I would give my experience with
blue haze.
We had our Gi's and other small tissue bx's showing blue haze. After trying
every thing we could change we did not have much luck until one day some one
had mentioned too much Sta-on in the waterbath could make the tissues blue.
I was able to demonstrate this on a bx with no bluing. We had been using 10
ml Sta-on in 2000 ml water. We now only put 4 ml per 2000ml water and have
had no problems since.

Allowing the biopsy to dry before placing in fixative. Leaving the specimen
jar on a window sill allowing it to overheat. Maybe a jar of old or expired
fixative. Many offices or employees of other departments are not as
informed on how to handle specimens as they should be.
